If g(x) = 725, which of the following is true?
kotykmax [81]

Answer:

B and D

Step-by-step explanation:

The g(x) = 725 makes no sense to me....

however g(x)  =  -2x/(x-3)  can be solved by plugging x = value into function

a)   g(x)  =  -2x/(x-3)

     g(0)  =  -2(0)/(0-3)  = -3

             =    0/-3  = 0  ≠  -3      FALSE

b)  g(x)  =  -2x/(x-3)  = 1

    g(1)  =  -2(1)/(1-3)  = 1

           =  -2 / -2  =  1  equals 1   TRUE

c)  g(x)  =  -2x/(x-3)

    g(2) =  -2(2)/(2-3)   <  g(4)  =  -2(4)/(4-3)

           =   -4 / -1          <   -8 / 1

           =     4    is greater than   - 8       FALSE

d) g(x)  =  -2x/(x-3)    both values were already calcuated

   g(1)  =  -2(1)/(1-3)  = 1      <    g(2) =  -2(2)/(2-3)  =  4

                                  1     <        4      TRUE
